3 Claims.

This invention relates to metal brick forms for brick work, comprisingthe combination of a standard size brick secured into a box-like casinghaving a front panel that may be plated or finished in any decorativeand ornamental feature as may be desired,

One of the salient features of this invention, is the adaptability ofapplying these metal forms for the ornamental finish on the exterior ofapartment houses, particularly around the doors If and Windows, and forfronts of business buildings on the ground floor, mezzanine and to thesecond floor, and for tax-payers fronts. For the inside of all types ofbuildings, these metal forms ar applicable for bath-rooms, kitchens,halls, and other places requiring streamline or modernistic finisheswhich provides a finish requiring little cleaning.

Another salient feature of this invention, is the adaptability ofproviding durable and substantial fronts for fire-places, colonnades,and walls for the interior and outside of buildings, in which border andintermediate linings may be applied and spaced to suit.

Another salient feature of this invention, is the ornamental finish onthe front panel portion of these metal casing forms, such as plating,polish surface, gun-metal and imitation of any interior decoratingfeature, such as Bakelite, Vitrolite, amber and burnish finish.

Another salient feature of this invention, is the elimination of whitesalt-peter stained brick walls, in which these metal forms may have thefinish of any type of brick finish.

One of the salient features of this invention, is the combination of themetal casing and the standard size brick, cement block, and the like,and in the metal casing alone for replacing tile work, in which thefilling 3' may be of special cement or the like, and is similar inproduction as the metal front casing forms for a product for buildingand home construction work.

A further salient feature of this invention, is the durability of thesemetal casing forms into which the brick of inexpensive grades may beinserted and secured, and are laid similar to any kind of brick work,are substantial where erected, beautify, hide the seams, do not crackand keep joints straight.

Other features of this invention will appear as the description proceedsin the following specification, accompanied by the annexed drawings, inwhich Fig. 1 is a perspective view of the metal casing front finish forbrick work.

Fig. 24 is a modified longitudinal sectional view over Fig. 3.

Referring to the drawings, particularly to Figures 1 to 7, a metalcasing l is shown, into which is secured the brick 2 onto a specialcement filling 3 set in a triangular or converging trough and channelportions 4 and 4' having a bottom or front panel 5 and end walls 6 andside walls 1, which secure the brick integrally in one product as shownclearly in Figures 4 and 5.

In Figure 17 is shown the cut blank B that is extended and finished intothe metal casing and box-like member I as shown in Figure 18. The dotand dash lines b and c, d and e, indicate the forming lines to make thetrough and channel portions 4 and 4, end walls 6 and side walls I,clearly shown in Figures 1 to '7. The blank B has corners out out atreflexed angles as shown to provide flaps 6c and 1c for the mitering thejoints Ill interconnecting at the intersection of the trough and channelportions which may be welded or secured in desired manner, such as byoverlapping portions l2 and I4 shown in the alternative blank form B ofFigure 19* and formed in the extended position as shown in thefragmentary view of Figure 20, the flaps l2 and [4 being welded,soldered or secured in any manner desired.

In Figures 6 and '7, a perspective is shown of the corner metal casingand brick form [5, which is produced similar to the wall form I shown inFigures 1 to 5. In this corner form an end portion provides for the endpanel 5a, adjoining at a right angle to and integrally with the sidepanel 512, these panels to be known also as the short and long panels 5aand 5b, respectively. The end and side panel portions are provided withinterconnecting trough and channel portions 4 and 4", and walls 6' andI, the wall 6a being adaptable to be open as per dotted lines to insertand secure the brick into the boxlike chamber of the casing 15.

Figure 8 shows a perspective View of a metal casing and brick form lc,which provides the headers that may be applied in the brick laying everysixth or seventh row. I

In Figures 9 to 12, a metal front casing le is shown, and is adaptablfor use to substitute tiling, in which the walls 6 and I may beeliminated, the special-cement trough and channel portions 4a and 4b aresecured to fresh cemented or plastered wall W, clearly illustrative inthe drawings.

Figure '13 shows an alternative design for a front metal casing lghaving an inner opening 30 for any desired ornamental feature.

Figure 14 shows a front metal casing form lh for cement blocks, or thelike 32, and in Figure 15 an alternative design for end metal casingforms llc are shown having an intermediate filling 34 of any suitablematerial, or bricks between the metal casings.

In Figure 16 an alternative form lb is shown over that shown in Figures9 to 12, the trough and channel portion being replaced by flaps or tabs35 that may be bent as per dotted lines to be secured to thespecial-cement filling forms that may be of any kind of mass material.

The boxlike casings I and I may be made from any suitable material, suchas Bakelite, white metal, molded glass, as shown in Figures 5d and 5c",and may be cast and formed as is, or otherwise than shown and described.

' The metal brick forms and products I are laid similar to the usualbrick work, the mortar being applied in between the metal brick forms asshown in Figures 1 and 2, the triangular trough and channel portionsbeing useful for two purposes, to keep the cinder-cement filling securedonto the panel section 5, and to provide the necessary space betweeneach metal brick form for the mortar 40. struction is shown in dot anddash lines in which the bricks are indicated at and the mortar at 46,which maybe, for example, a twelve-inch wall.

Also it may be understood, while I have shown the metal casing orboxlike member securing the brick which has been inserted into the freshcinder-cement filling 3, the brick may be formed therein, baked andhardened, and the front face of the panel 5 of the metal casing, may bepolished, chrome plated, pastel, copper or ivory finish, enameled in anycolor, or lacquered, in addition to those finishes hereinbeforementioned.

In the manufacture of this metal brick, block and tile forms, thedescription of the forms in'the drawings are preferable, but alterationsmay be made in the shape of the trough and channel sections, 3, thepanel 5, and walls 6 and I, and in modifications shown, all similarparts to the metal brick forms shown in Figures 1 to 7, the samenumerals will be primed in the alternative forms.

In Figure 23, the blank for the corner brick form is cut as shown with along panel Ba and flaps 6a", 611" and 1a", and when bent and formed onthe dot and dash lines D, c, e, d and b", c", e", d" and 1, form theface panels 5a and 5b adjoining each other at a right angle, walls 611,la, 6a and 6a" and troughs and channel portions 4' and 4" shown inFigures 6 and 7. The adjoining panels are plated, coated and finished inany desired decorative manner.

In Figure 24 (Sheet 1), the triangular trough and channel portions 4 and4 have been omitted, flanged or seamed portions have been substituted toprovide for the working space of the mortar 40. This alternative formhas been shown for the reason I do not wish to confine my invention toone form, and may make any alteration therein if same comes within thescope of the appended claims.

Having thusv described my invention, what I claim as new and desire tosecure by Letters Patent, is as follows:

1. In a blank having the corners cut out at a reflex angle, said blankadaptable to be extended into a box-like member having a bottom withconverging trough and channel portions and extending side and end wallportions, said corners portion of said blank forming a mitre joint atthe intersection of said trough and-channel portions, said trough andchannel portions adaptable to have a special cement filling placedtherein, and a brick and the lik adaptable to be secured thereon andbetween said side and end wall per-- tions.

3. In a blank having cut out portionsadaptable to be extended into abox-like member forming" The inside brick work and conface panels at aright angle to each other, said blank haivng a long and short panel withflaps when bent and extended form said face panels, said blank formingconverging trough and channel portions having a mitre joint at thecorner portions thereof and extending wall portions above said troughand channel portions, said trough and channel portions of said box-likemember adaptable to have secured therein a special cement filling uponwhich may be further secured a brick form and the like, said box-likemember with said face panels at right angle to each other providing acorner brick form and the like.
